Symmetry of divisibility in elementary divisor rings. (Ukrainian. English summary) Zbl 1093.16025
Summary: K. Asano [J. Math. Soc. Japan 1, 73-78 (1949; Zbl 0037.30605), Osaka Math. J. 1, 52-61 (1949; Zbl 0041.16503)] and T. Nakayama [Proc. Imp. Acad. Jap. 16, 285-289 (1940; Zbl 0024.09904), ibid. 17, 53-56 (1941; Zbl 0026.05802)] proved for a semilocal ring the statement: if \(Ra=bR\) is an ideal of the ring \(R\), then \(Ra=aR=bR=Rb\). In the paper this result is generalized for elementary divisor rings.
